SPECIFICATION formingpart of Letters Patent No. 667,165, dated January 29, 1901.

Application filed April 17, 1900. serial No. 13,257. Lllo model.)

To @ZZ whom it may concern.

Be it known that I, FRANK L. CARTER, a citizen of the United States, residing at Dorsey, in the county of Howard and State of Maryland, have invented certain new and useful Improvements in Hydrocarbon-l3urn ers; and I do declare thefollowing to be a ifull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and ,use thesa'melf.reference being had tothe accompanyingidrawings, land to the figures of reference marked thereon, which form a part of this specification. l

lThis invention has relation to hydrocarbon-burners, and has for its general object to provide an 'improved burner of this class adapted for use in ranges, cooking and heating stoves, furnaces, grates, andother analogous structures.

A special object of the invention is to pro vide improved means whereby the air supplied to the combustion-chamber to facilitate combustion will be heated before cming into -contact with the unconsumed vaporized oil View to economy of construction and ready separation or assembling of the parts to facilitate taking down andv setting up for repairing or other purposes.

'Vith these objects in View the invention consists in the improved construction, arrangement, and combination of parts of a burner of the class specified, all fullydescribed hereinafter an d afterward specifically claimed.

In the accompanying drawings, in which the invention is illustratedas of a form suitable for use in an oblong re-box, such as is common in cooking-stoves and ranges, Figure 1 is a perspective view of a burner construct# ed in accordance with this invention. Fig. 2 is a central longitudinal vertical sectional view of the saine on the plane indicated by the broken lines t of Fig. 3. Fig. 3 is a horizon tal sectional view,'slightly reduced in scale, on the plane indicated by the broken lines y y of Fig. 2 looking downward, as Aindicated by the arrows. Fig. 4 is atop plan view of the base-plate on a still further reduced scale.

`Like parts are indicated by the same numerals in all the figures of the drawings.

Referring to the drawings by numerals, 1 indicates the base-plate, which is provided with avertical peripheral flange 2, making it serve The purpose of a pan, as hereinafter specified. The plate i is provided with openings 3 3 and 4 4, su rrounded on the upper surface of the plate by lianges 5 of substantially the height of flange 2. These openings are shown circular and as of two series 3 3 and '4 4 on either side of the longitudinal center of the plate.r Their shape, however, the number in each series, and the position of each series may be Varied to suit the particular circumstances of each case. As before stated, this -plate lis the base-plate ol' the burner, and it also forms the base or bottom of a chamber 6, .which chamber is completed by the addition of a top plate 7, having a depending peripheral flange 8 fitting inside the peripheraiflange 2 of the base-plate. Itop plate 7 are provided two longitudinallyarranged rows of small holes or perforations 9 10, so placed as to be out of register or ont of vertical alinement'with openings 3 3 and 4 4 of the base-plate, the rows of perforations 9 and lO being preferably nearer to the sides of the plate 7 than are the openings 3 Sand 4 4 to the sides of plate l.

11 12 designate two chambers or retorts preferably of oblong rectangular form and of a length 'somewhat less than the width of chamber 6, such form and size being variable when desired within reasonable limits. 'lhese chambers are mounted centrally and transversely'at and upon the ends of the top plate 7 of chamber G and are secured thereupon in any suitable manner-as, for instance, by means of bolts 13, passing through plate 7, and suitabie horizontal lugs or flanges 14, projecting from the bottom of the chambers.

In the inwardly-facing side walls of the chambers 1l and l2 are formed vertical grooves 15 16 .to receive vertical fianges 17 18 on the end walls oi' a combustionchamber19, said grooves being closed at their lower ends, so that the lianges 17 and 18 may not pass entirely through them, whereby the chamber 19 In thev IOO partial cover 21, provided with a central open.

ing, as hereinafter mentioned.V l

22 indicates a pipe tapped into `retort 11, leading from any suitable supply of oil, (not shown,) which pipe may be provided with any su'itablevalve for regulating the supply of o il.

23 indicates a horizontal pipe connecting retorts 11 and. 12, being tapped' into the inner walls of each.

211 indicates a pipe tapped into the inner wall of retort 12 and lying` in substantiallyv the same horizontal plane as pipe 23, as at 25, .to near the retort 11, where .it is curved back, as at 26", and led to the'center of chamber 19, where it bends into vertical position, as at 27, its upper end being threaded and projected Vthrough the' centralnopening in the partial Acover 21 of chamber l9,before mentioned. The

pipe 23 and the part 25 of pipe 24 lie just within the lower edge of chamber 19, and the walls of that chamber are notched at 28 to admit seid pipes. i

The burner proper is indicated at 29 and consists,. essentially, of a horizontal pipe closed at its ends and provided with nozzles 30 31, depending vertically therefrom over the openings in the top of chamber19. The burner proper in this instance is shown as of two short lengths of pipe, as at 32, with caps at'their outer ends and connected by a T-fitting 34, the stemof which 'depends in line with the nozzles and is arranged to be threaded on the projecting threaded end ofthe vertical portion 27 of pipe 24:. When thus attached',` the burner bears upon' the partial cover 21 of chamber 19, th us securely holding the danges 17 18 downin the grooves 15 and 16 and securing the chamber 19 in place. Owing to the forml of pipe 24, to which theburner 29 is secured when thus acting as a clampingnut, said pipe will be to a certainement elas- -tic and yielding, so that any upward expansion of. the walls of chamber 19-due to heat will be compensatedfor land all tendency, to strip the threads of part 27 of pipe 24. or of the T-fitting 3a will be avoided.

.A In'operation to start a reoil is permitted to .flow through the pipes, retorts, and nozzles and to drip upon plate 7, where it is ignited. The dame impinging upon the various parts Will heat them, so that the oil will soon` begin to issue from thev nozzles in the form of aninflammablegas or vapor and the jets of tlamewill be projected downward into lthe chamber 19 and into contact with all the parts of the burner, heating them to a high degree. The y jets will causea downdraft through the openings in the top of the con1` bustion-chamber, which will supply the oxygen necessary to support combustion, and the products of combustion will pass out of the combustion-chamber through spaces, taking an upward' course between the walls of the chamber' and the walls of the iire-box in .wh ich the device is used.. Wit-heut the airheating chamber these products of combustion in passing out through spaces 2O would strike 'an upward draft of atmospheric air between the Walls'of the'chamber and rebox and the con-tact therewith would tend to chill tHeY-vapors andto condense any unconsumed gas. "In such usual construction this mixed air and thechilled vapors wouldv pass up and part of the mixture be again carried through the combnstion -chan 1ber, the air in the mixture supplying the necessary-oxygen. With the air-heating chamber there would be no side. draft of cold air. The air for such side draft Willbe heated in its passage through theheating-chamber, so thatwhen the vapors yof combustion mix with it there- Will be .no chilling and no condensation of unconsu med gases, thus materially facilitating perfect combustion, the result being, as ascertained by practical use, .a perfect blue {iame and almost en tire absence of'soot or other residunm.

'The location of openings 3 3 and 4.4 and perforations 9 10fout of vertical alinement with each other retards the passage of air out of perforations 9 l0before being properly heated. The oil in passing through. the retort 11 will` be partially orwholly vaporized and the vaporization will be perfected. in the passage of oil or vapor through pipe 23 retort 12, pipe 24, and theburner, the vapor being retarded,

dried, and snperheated in its passage through the second retort 12, and this condition being preserved and continued during its further -ilanges 2 and 5 until it is vaporized, passed through'perforati'ons 9 1Q, and consumed,

IIO

thus preventing it from dripping down into the {ire-box or ash-pit and being wasted;

The advantages attending the use of this burner will be obvious from the foregoing description of the construction and operation,

and it will bf'e further obvious that slight changesin the construction and'arrangement of the part-s might be made Without departing from the spirit and scope of the invention.

Having thus fully described the invention, what I claim as new, and desire .to secureby Letters Patent of the United States, is-f` 1.
